Key Parameters

Substitute Part Grouping Explanation

Substitution of the SLP331M420H5P3 is determined by strict equivalence of the following parameters:

• Capacitance: 330 µF (identical across all substitutes)
• Tolerance: ±20% (identical across all substitutes)
• Package / Case: Radial, Can - Snap-In (identical across all substitutes)
• Lead Spacing: 0.394" (10.00 mm) (identical across all substitutes)
• Size / Dimension: 1.378" Dia (35.00 mm) (identical across all substitutes)
• Height - Seated (Max): 1.457" (37.00 mm) (identical across all substitutes)
• Mounting Type: Through Hole (identical across all substitutes)
• Operating Temperature Range: -25°C ~ 105°C (identical across all substitutes)
• Polarization: Polar (identical across all substitutes)

The identified substitutes feature upgraded voltage ratings (450 V vs. 420 V), providing increased operational margin in high-voltage applications while maintaining dimensional and functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are ROHS3 compliant and REACH unaffected, meeting the same regulatory requirements as the original SLP331M420H5P3. The 450VXG330MEFCSN35X35 (Rubycon VXG series) offers an extended lifetime of 5000 hours at 105°C with elevated ripple current capability at 120 Hz (1.65 A). The LQS2W331MELC35 (Nichicon LQS series) maintains the 3000-hour lifetime specification with lower ripple current at 120 Hz (1.38 A). Both substitute parts feature upgraded voltage ratings of 450 V, providing 30 V additional safety margin over the original 420 V specification while remaining mechanically and electrically compatible with circuit designs specified for the SLP331M420H5P3.

Frequently Asked Questions (FAQ)

Q: Can the 450VXG330MEFCSN35X35 or LQS2W331MELC35 be used as direct replacements for the SLP331M420H5P3?

A: Yes. Both substitute parts maintain identical capacitance (330 µF), tolerance (±20%), package configuration (Radial, Can - Snap-In), physical dimensions (35 mm diameter, 37 mm seated height), and lead spacing (10 mm). The higher voltage ratings (450 V) are backward compatible with 420 V circuit specifications.

Q: What is the difference between the two substitute options?

A: The 450VXG330MEFCSN35X35 features an extended lifetime of 5000 hours at 105°C and higher ripple current capacity at 120 Hz (1.65 A). The LQS2W331MELC35 maintains a 3000-hour lifetime equivalent to the original part with slightly reduced ripple current at 120 Hz (1.38 A).

Q: Are dimensional and mounting characteristics identical?

A: Yes. Both substitute parts share the same snap-in package geometry, mounting configuration (through-hole), lead spacing (10 mm), can diameter (35 mm), and maximum seated height (37 mm) as the SLP331M420H5P3.

Q: What is the functional impact of the higher voltage rating?

A: The 450 V rating provides additional electrical stress margin in applications using 420 V components. Circuit designs remain functionally equivalent. No design changes are required.

Q: Are regulatory certifications equivalent?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting identical environmental and regulatory standards.
